When it comes to the emblem of Hanoi, everyone immediately thinks of the Temple of Literature's Pavilion of the Constellation of Literature (Khuê Văn Các). However, many may not know that the ancient logo of Thang Long – Hanoi dates back to 1888.
Meaning of the emblem: "This bas-relief is a symbol bearing the traces of old Hanoi, originating from 1888. The two dragons are tied to the city's name, Thang Long (Ascending Dragon). At the center lies a sacred sword, also a symbol of peace. Flanking the relief are branches of oak and olive leaves. The oak represents strength, while the olive symbolizes prosperity and wealth." – Trần Hậu Yên Thế. Key sites preserving traces of this ancient Hanoi logo include: the temple of King Lê Thái Tổ, tied to the legend of Hoan Kiem Lake; Long Bien Bridge (1889–1902, with the bridge's inauguration in 1902, the French minted a medal featuring the ancient Hanoi logo); the "Con Cóc" flower garden (Bát Long Garden); and Trung Vuong High School.
VILLE DE HANOI. Crowned arms of the city of Hanoi on a banner inscribed "DIS LECTA FORTITUDINE PROSPERA."
Today, in Hanoi, only one place remains—and stands as the highest—that preserves this ancient emblem of Hanoi: Trung Vuong High School, where many illustrious Vietnamese figures once studied.
